DNTT and gastric cancer: Our results were consistent with the findings of metabolically active cell detection assay, plasma membrane integrity assay, TdT labeled cell detection, apoptotic cell sorting by fluorescence-activated cell sorting (FACS), caspase activity assay, immunoblotting, and soft agar assay, all of which showed that ufUJ induced ER stress/caspase activation-mediated apoptosis or necrotic cell death of gastric cancer cells.
